This HPS Performance cold-side charge pipe kit replaces the factory OEM plastic cold-side charge pipe as an essential upgrade. The 3.5-inch custom mandrel-bent stainless steel tubing allows more air to flow into the engine while significantly reducing EGTs. This kit features 4-ply reinforced oil-resistant fluoro-lined silicone boots designed to withstand the harmful effects of oil blow-by commonly found in 6.6L Duramax diesel LML engines. The kit also includes stainless steel spring-loaded T-bolt clamps that accommodate temperature and pressure fluctuations during operation without the risk of boost leaks.
Before You Order
〇Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please confirm whether the part is compatible with Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model on our top page, this does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for delivery. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural strength documentation for the purposes of the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please check the contents immediately upon receipt of your order. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through our company." Please note that we do not provide support through other companies or distributors located in Japan.
